基于LabVIEW的机床振动信号的分析系统

LabVIEW是当今虚拟仪器开发最流行的一种图形化编程语言。结合机床振动信号的特点,以LabVIEW 8.5为开发平台,设计了机床振动信号的分析系统。系统由硬件和测试分析软件两大部分组成。软件作为虚拟仪器的核心,由控制底层硬件管理模块与分析功能模块组成,完成虚拟仪器特定的逻辑分析处理过程。信号经过LabVIEW处理后实现了频域、时域分析、相位分析、谱分析、相关性分析等多种功能。相对传统测试方法,本测试系统的灵活性显著增加,测试费用、能耗大大降低。实践证明本系统的测试效果良好。

Analysis system of machine vibration signal based on LabVIEW

LabVIEW is a graphical programming language which is the most popular one in today＇s virtual instrument development.A kind of analysis system of machine vibration signal is designed based on LabVIEW 8.5,with the characteristics of the signal.The system consists of hardware and test analysis software,as the core of virtual instrument,which consists of controlling hardware management module and analysis function module,completing virtual instrument-specific logic analysis process.Signal is processed with LabVIEW and a variety of functions are realized,such as frequency domain analysis,time domain analysis,phase analysis,spectral analysis,correlation analysis,etc.Compared with the traditional test methods,a significant increase in the flexibility of the test system is realized.Test costs and energy consumption are reduced by the system.The good test results show that the system works well.
